Perform the test of hypotheses indicated, using the data from independent samples given. Use the critical value approach. Compute the p-value of the test, as well. Test H 0 : μ 1 − μ 2 = 45 vs. H a : μ 1 − μ 2 > 45 @ α = 0.001: n 1 = 200, x - 1 = 1312, s 1 = 35 n 2 = 225, x - 2 = 1256, s 2 = 28 Test H 0 : μ 1 − μ 2 = − 12 vs. H a : μ 1 − μ 2 ≠ − 12 @ α = 0.10: n 1 = 35, x - 1 = 121, s 1 = 6 n 2 = 40, x - 2 = 135, s 2 = 7
